Fuckin' Illinois Shit Head Towing a Boat - Refers to rude, clueless Illinois resident(s) (usually Chicago suburbanites) who not only have no clue as to courteous driving, but further exemplify it while towing a massive boat.

Fucking Illinois ShitHeads Towing A Boat. This is a term used mainly by Wisconsinites when describing a ridiculus driver from Illinois who vacations in Wisconsin in the summer to use a boat on the beautiful lakes. They are known to drive like shit on the roads while towing their boats.

I was driving through town and a fish tab was taking up two lanes with his boat trailer so I could not get around him.

Fucking Illinois shithead towing a boat. Used to refer to the thousands of people from Illinois that cross the state line every weekend to litter and treat Wisconsin lakes like shit. Often caused by realization that Illinois has absolutely nothing to offer.

"Hey did you just see that Fish-tab throw a bag of McDonald's shit out of his window?"
"Yep, big surprise."
